← ScienceWhich outcome occurs when thermal gradients increase vacancy diffusion within a crystal lattice?
A)Enhanced creep deformation develops rapidly✓
B)Increased fatigue strength is observed
C)Faster corrosion resistance degrades material
D)Higher thermal expansion coefficients result
💡 Explanation
Enhanced atom mobility increases the **creep deformation** rate because increased temperatures reduce material yield strength, therefore creep deformation develops rapidly, rather than strength improvements which require decreased mobility and lattice disruption.
